The US has funded $1.5 million (£1m) to tackle air pollution in the city of Oregon.

The Oregon Department of Environmental Quality (DEQ) will use the funding to remove air pollution from diesel-fuelled activities around its Port in Portland.

The projects will replace 23 heavy-duty diesel trucks which travel more than 1.3 million miles a year. It will also add diesel filters to cargo equipment, two tractors and an aerial lift.

Administrator Gina McCarthy from the Environmental Protection Agency (EPA) said: “Every dollar we invest in clean diesel generates between $7 (£4.60) and $18 (£11.90) in public health benefits. By promoting clean diesel technologies, we can help save lives locally and play a leadership role on climate change globally.”

The project expects to reduce carbon dioxide by 6,000 tons along with others.
